Buying guide for Best Christmas onesies

Some people like Christmas sweaters, but if you want to stay as cozy as possible, Christmas onesies are where it's at. If you're planning a low-key Christmas where you snuggle up, watch festive movies, and eat a mountain of food, a Christmas onesie is the perfect outfit. You don't even need to worry about the waistband digging in when you overindulge because there isn't one!

The design of a Christmas onesie is objectively what matters most of all. You can find a huge range of onesies, from subtle festive designs to full-on Santa suits, so you're bound to find one you love. It's important to choose a onesie that's the right size for the wearer. It shouldn't be too tight, as comfort is key, nor should it be ridiculously oversized. You also have other features to consider, such as whether you want feet, a hood, or a back flap.

Check the tags for washing instructions — most Christmas onesies are suitable for machine washing and tumble drying on low, but it's always best to confirm.

Key considerations


Christmas onesies are available in a range of sizes for kids and adults. Occasionally, you'll find a one-size adult onesie, but this can lead to the onesie being too big for some wearers, too small for others, and a perfect fit for just a handful of individuals. If you know your usual size, that's great, but you may want to size up one or two sizes since onesies are more comfortable when they're nicely baggy.

Another issue is that some onesies aren't completely true to size, so you might buy one size up from your usual and find that it's significantly too small. If possible, we recommend taking your measurements and consulting the sizing chart for a proper fit.


Here comes the fun part: the design of your Christmas onesie. A quick search will uncover all kinds of festive designs, so it can be hard to narrow it down if you don't already have a design in mind. Some Christmas onesies are costume onesies designed to turn you into a festive character. For instance, you can find reindeer onesies that are mostly brown with a white chest and antlers on the hood and Santa onesies consisting of the classic red and white suit with faux fur at the collar and cuffs. Then you have patterned onesies that feature festive patterns all over. Common Christmas onesie patterns include snowflake and reindeer prints, Christmas trees, and gingerbread men.


Choosing the right material makes a huge difference in your overall comfort. Fleece onesies are a common option. They feel extremely soft and keep you warm, but the problem is, they make many people feel overly warm. Unless you live in an area where winters are exceptionally cold, you might want to avoid a fleece onesie.

Cotton jersey onesies are made from a t-shirt type material that's naturally breathable so you won't overheat. If you expect mild weather for the holidays or are likely to have your thermostat turned way up, cotton jersey is your best bet.

Cotton flannel is the type of material used to make flannel shirts and flannel pajamas. It's warmer and cozier than cotton jersey but breathable, like all cotton fabrics. This allows you to feel comfortably warm without overheating.

You may find it convenient to have pockets in your onesie to store your phone or pieces of Christmas candy.




Some Christmas onesies have integrated feet. If you want the coziest onesie around, you might prefer an option with feet. Unless removable, however, the feet can be impractical at times. For instance, if you want to slip your shoes on to take the garbage out, the feet might not fit in your shoes, and if you step in a spill, you'll need to change out of your onesie or put up with wet feet. 


Not only do hoods add an extra level of warmth and comfort to a onesie, some enhance the design by featuring ears or antlers.

Closure type

The majority of Christmas onesies have zip closures, making them easy and quick to open and close. Occasionally, you'll find onesies with buttons or snaps, but this is far less convenient.

Did You Know?
Footless onesies generally have cuffed bottoms, making them easy to turn up if the legs are too long.


Ugly Christmas sweaterIf you like Christmas onesies, it stands to reason that you might also be a fan of Christmas sweaters. After all, you might not want to spend the whole day in your onesie, and you'll need something festive to change into.

Christmas garlandA Christmas garland is another Christmas decoration must-have. Garland is perfect for trimming doorways, stair banisters, mantelpieces, and anywhere else you can think of. 

Christmas stockingsNot only do Christmas stockings give Santa a place to leave gifts, they make great decorations during the festive season.

Christmas onesie prices


At the low end of the spectrum, you can find Christmas onesies for between $15 and $30. Some of these will be small onesies for toddlers and little kids, but you can find a handful of adult options at the higher end of the range.


You can find a nice selection of festive onesies for $30 to $50, including a range of sizes, designs, and materials.


The priciest Christmas onesies cost between $50 and $80. These are often in large sizes with more elaborate designs.

While most modern onesies forgo the traditional back flap, you can still find a handful of options that sport one. With a back flap, you aren't forced to fully undress when you need to use the bathroom.



  • Check out the zipper. Make sure the zipper on your onesie goes down far enough that it’s easy to remove. That way, bathroom trips won’t be too much of a hassle.
  • Consider a onesie for your dog. If you have a canine companion who's just as much of a member of your family as your human relatives are, you can find a handful of Christmas onesies that have matching options for dogs.
  • Think about doing laundry. Hood bobbles and pompoms on the drawstrings of onesies might look festive, but they don't always wash well, so bear that in mind.
  • Order early. Not 100% sure on the fit? Order your Christmas onesies in enough time that you can return them and order a larger or smaller replacement before Christmas if needed.
Comfort is paramount in a onesie, so be sure to choose one that's made from soft material, isn't too tight, and doesn't dig in.


Q. Is it a waste to buy a Christmas onesie that I'll only wear for a single day?

A. The problem with all Christmas-themed garments is that you get limited use out of them, which can seem like a waste. Of course, the choice is yours to make, but you might get more use out of your Christmas onesie than you'd imagine. First off, you have the whole Christmas season to wear it, not just Christmas Day. Plus, you can use it in future years, unless you're buying for a child who will likely outgrow their onesie by the following year. You can also opt for a subtle design such as snowflakes, stars, or plaid, which you might feel better about wearing all winter rather than just at Christmastime.

Q. Can I wear my Christmas onesie outside?

A. If you want to wear your Christmas onesie out of the house to a festive costume party or on a caroling excursion, there's no reason why not, as long as you wear extra layers if it's cold out. Children are often inclined to wear their Christmas onesies to the store or to school, and the festive season isn't the time to talk them out of it.

Q. Are the feet on Christmas onesies removable?

A. Do you like the look of a Christmas onesie that has feet but you don't want feet on your onesie? This is quite a dilemma because you're left with the option of not buying a onesie you like or compromising on the feet. It's worth carefully checking the product description before buying, however, because some onesies with feet give you the option of removing the feet. However, this isn't true of all onesies with feet, so don't assume they'll be removable.
